I recently noted the successful Kickstarter campaign to support a documentary on Bill Nye, the Planetary Society CEO and Science Guy. Like Neil deGrasse Tyson, Carl Sagan was an influence on Nye, and it makes sense that a film on Sagan has attracted interest. (No word yet on a Tyson documentary, and I don’t know one way or the other if Tyson would be so inclined.)
Variety reported last week that the Warner Bros. studio has expressed interest in a film on Sagan’s life (the studio also produced the movie based on Sagan’s novel Contact). Sagan’s widow Ann Druyan will produce, along with Lynda Obst. Obst was a producer on the Christopher Nolan film Interstellar as well as Contact. Druyan was heavily involved with the 2014 edition of Cosmos. Zach Dean has been attached to the project as writer (though it’s not unheard of for a film to change writers between the beginning of a project and the start of principal filming). His major screenwriting credit to date is the crime drama Deadfall.
This arrangement also means that the film would be along the lines of The Theory of Everything or The Imitation Game. In other words, a film focused on the life of a scientist that will serve the story first. How it treats the history will be uncertain, and could undercut whatever interest comes from the scientific community when its heroes are chronicled.
